BPECIFIGATION forming part of Letters Patent No. 783,551, dated February .28, 1905.

Application filed December 9, 1903. Serial No. 184,386.

To a, 107112121177 'm/rty concern:

Be it known that we, CARL A. Srruss and J OSEPH (I. H'EIN, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful improvement in Fruit-Jars, of which the following is a de scription, reference being had to the accompanying drawings, which are a part of this speciiication.

Our invention relates to certain new and useful improvements in fruit-jars, and has for its object to provide a closure for a jar or other receptacle by which the cover may be easily and quickly applied and removed and which will be perfectly tight when scaled.

With the above and other incidental objects in View the invention consists of the devices and parts or their equivalents, as hereinafter set forth.

Referring to the accompanying d rawings, in which like characters of reference indicate the same parts in the several views, Figure l is a vertical section of a jar-closure, illustrating our invention. Fig. 2 is a transverse section thereof, taken on the line 2 2 of Fig. 1; and Fig. 3 is a side elevation showing the open socket connection, the clamping-screw being broken away.

In the drawings, 7 represents a jar or other receptacle of glass, porcelain, or other desirable material, provided with the slightly-contracted neck portion 8, producing the external shoulder 9.

An inverted-cup shaped cover 10 has its depending peripheral flange 11 resting on a resilient gasket 12, of rubber or suitable material, which is seated on the shoulder 9, the neck 8 of the jar telescoping within said flange 11.

On one side of the jar 7, just beneath the shoulder 9, is an indentation or socket 123, which may be of any suitable shape, but is prcferabl y, as shown, with a horizontal upper wall and an inclined lower wall, the inclined inner wall of the indentation merging with the inner surface of the neck portion 8 of the jar, leaving the solid block of material between the socket and the shoulder 9. ()n the opposite side of the jar is a similar indentation or socket lei; but one side thereof is open, the indentation varying in depth as determined by a curved line in the shape of an are about the socket 13 as a center and ending abruptly in a stop-shoulder 15.

A clamp member 16, preferably of sheet metal and of a U shape, has its ends bent inwardly to form engaging hooks l7, and through a perforation in its enlarged central portion is threaded a clamp-screw '18, having a ring 19 passed through its perforated upper end.

The bail-like clamp member 16 is adapted to have one of its hook ends 17 placed in the socket 123, and said member is then swung on said hook end as a pivot, so as to enter the other hook end 17 in the open socket lei. When such swinging motion is limited by the engagement of the hook end 17 with the stop-shoulder 15, the clamp-screw 18 is turned down by means of ring 19 into engagement with the cover 10, and the continued turning of said clamp-screw tightly clamps the cover 10 and shoulder 9 together, and the interposed rubber gasket 12 being compressed between them effectually seals the jar. hen it is desired to remove the cover 10, it is only necessary to loosen the screw 18 and swing the clamp member 16 on the hook end 17, which is seated in the pivotal socket 123, so as to remove the other hook end from socket M, and the cover is again free to be removed.

From the foregoing it will be seen that we have pro vided a jar-closure by which the cover may be clamped with great pressure without danger of the parts slipping or breaking and which may be quickly and easily applied or removed W hat we claim as our invention is 1. In a jar-closure, a jar, a cover therefor, a clamp member having hook ends and pro vided with means for engaging the cover, said jar having a socket in which one end of the clamp member may be pivotally mounted and having another socket into which the other end of the clamp member may be entered and seated byswinging said clamp member pivotally in the lirst-mentioned socket.

2. In a jar-closure, a jar having a pivotal socket on one side and an open'socket on the other side, a cover for the ar, a clamp member having hook ends, one hook end adapted to turn in the pivotal socket and thereby swing the other hook end through the opening of the other socket, and means carried by the clamp member to bear upon the cover.

3. In a jar-closure, a jar having a pivotal socket on one side and an open socket on the other side in the shape of an arc with the pivotal socket as its center, a cover for the jar, a clamp member having hook ends, one hook end adapted to turn in the pivotal socket and thereby swing the other hook through the opening of the other socket into engagement therewith, and means on the clamp member to bear upon the cover.

4. In a jar-closure, a jar having a reduced neck forming a shoulder, a cover having adepending flange to be seated on said shoulder, a gasket interposed between the flange and shoulder, said jar being provided with indentations or sockets on its opposite sides just beneath the shoulder, one of said indentations having an open side and being shaped to an are on the other indentation as a center, said open-sided perforation having its other side swing the other through the open side of the other indentation and engage against the stopshoulder thereof.

5. In a jar-closure, a jar having a reduced neck forming a shoulder, a cover having a depending flange to be seated on said shoulder, a gasket interposed between the flange and shoulder, said jar being provided with indentations or sockets on its opposite sides just beneath the shoulder, one of said indentations having an open side and being shaped to an are on the other indentation as a center, said open-sided perforation having its other side forming a stop-shoulder, a clamp member provided with hook ends and adapted to engage one end in one indentation and swing the other end through the open side of the other indentation and against the stop-shoulder thereof. a screw threaded through the clamp member and adapted to bear upon the cover, and a ring carried by the screw.

In testimony whereof we afiix our signatures in presence of two witnesses.
